Beautiful view of Carcote area and "Chela" volcano (5648 meters above sea level) in the Background, and FCAB train goes around the great salt flats of Carcote, a rich deposit of various salts (chlorides, chlorates, nitrates, nitrides, boron, borax, lithium, etc.). Then comes a line through the middle of the salt, and then get to Ollagüe.. See this photograph (RP #442265) of the same place, but to another train and another time. How to change the colors of the salt and the environment, depending on the time of year: http://www.railpictures.net/photo/442265
